ERIC STANLEY BURROUGHS, OF LIVERPOOL, ENGLAND.

RUBBER STAMP.

Specification of Letters Patent. 7 Patented Dec. 16, 1919.

Application filed June 10, 1919. Serial No. 303,140.

To all whom it may concern:

Be it known that 1, E1210 STANLEY BUR- ROUGHS, a subject of the King of Great Britain, and a resident of Liverpool, England, have invented certain new and useful Improvements in Rubber Stamps, of which the following is a specification.

With the usual rubber hand stamps, besides the difficulty of recognizing the right way up of the stamp when holding the device by the handle, there is also the difliculty, where a number of stamps are in use, of picking out from a group the particular stamp required. The object of the present invention is to provide means such, that besides enabling the stamp to be correctly positioned, an immediate indication can be obtained as to the matter on any stamp of a series.

According to this invention, at the rear of the usual brass or other metallic back plate of the rubber stamp, I propose to fix an impression taken from the rubber stamp itself, this impression showing positively, and not reversed like the rubber stamp, the subject matter.

The invention is illustrated in the accompanying drawings in which Figure 1. is a vertical section of a rubber stamp in accordance with this invention, Fig. 2. being a plan view of the stamp with the handle removed. Fig. 3. is an isometric view of the several parts of the stamp back separated. Fig. a. showing a modified construction of the stamp back.

In carrying out the invention, in the preferred construction Figs. 1 to 3, the back 1 of the rubber stamp is made up of a plate of malleable iron or other material and a light thin brass or other sheet metal frame 2 of open construction, the edge of which is made of angled section, as shown in Fig. 1, having an upper overhanging flanged lip 3, and a transverse element a which knits together centrally the overhanging top flanges 3. Apertures 5, and 6 are formed in the elements 1 and 4E, respectively, for a screw 7 by means of which the back plate 1 of the rubber stamp may be secured to the handle 8. The rubber stamp itself, 9, is mounted on the back plate 1 after the latter has been fixed to the handle 8. An impression 10 is taken from the rubber stamp, say on a piece of paper or thin card, and this impression is placed on top of the back 1 and covered by a mica plate 11, themica Fig. I, so that the mica, cover is uppermost! An aperture 11 is also formed in them'ica plate and the screw 7 is then passed through the apertures in the elements to secure them to the handle. The impression. of the rubber stamp is set the right way up relatively to the stamp itself, so that an indication of the correct position of the rubber stamp may be seen on the back through the window 11. The mica preserves the impression and enables it to be kept clean, and as well as indicating the right way up of the stamp, the impression shows the subject matter positively and not reversed, thus enabling the required stamp to be readily picked out of a number of stamps.

In the modification Fig. 4, the impression 13 is fastened at the rear of the back plate 1 which in this case is provided with the usual integral tang 14 entered into the handle 8 and the impression 13 covered, preferably with a sheet of mica 11 to preserve it, the mica and the impression being cemented in place 011 the back plate 1. Perforations in this case also are formed in the mica and in the paper or cardboard bearing the impression through which the tang 14 is passed.

If desired, the top of the handle may be provided with a flat part 8 as shown by the dotted line Fig. &, and an impression or indication of the subject-matter of the stamp may be placed on this flat part to enable the nature of the stamp to be readily determined.

Instead of covering the impression with a sheet of mica it may be heavily varnished,

or otherwise treated so as to preserve it and keep it legible.

With rubber hand stamps provided as described with an impression at the back, therequired stamp may be readily picked out from a number and, further, the stamp may be correctly positioned instead of having to mark the back plate with the word Top or provide the handle with a brass or other metallic button for this purpose.

I claim:

1. A rubber hand stamp, comprising, a rubber stamp, a back plate for the rubber stamp, an impression of the rubber stamp fixed at the rear of the back plate, an open framing fitted over the impression, and

means for securing the back plate, the impression and the frame to the handle of the stamp.

2. A rubber hand stamp, comprising, a rubber stamp, a back plate for the rubber stamp, an impression of the rubber stamp fixed at the rear of the back plate, an open framing fitted over the impression, said framing having angle section edges to inclose the sides of the back plate, and means for securing the back plate, the impression and the frame to the handle of the stamp.

3. A rubber hand stamp, comprising, a rubber stamp, a back plate for the rubber stamp, an impression of the rubber stamp 15 fixed at the rear of the back plate, a trans parent protection plate over the impression, an Open framing fitted over the impression, and means for securing the back plate, the impression and the frame to the handle of the stamp.

In testimony whereof I afli'x my signature in presence of two witnesses.
